13. While CPU overheat is detected, the system will automatically shutdown.

Before you resume the system, please check if the CPU fan on the

motherboard functions properly and unplug the power cord, then plug it

back again. To improve heat dissipation, remember to spray thermal

grease between the CPU and the heatsink when you install the PC system.

14. EuP, stands for Energy Using Product, was a provision regulated by

European Union to define the power consumption for the completed system.

According to EuP, the total AC power of the completed system shall be

under 1.00W in off mode condition. To meet EuP standard, an EuP ready

motherboard and an EuP ready power supply are required. According to

Intel’s suggestion, the EuP ready power supply must meet the standard of

5v standby power efficiency is higher than 50% under 100 mA current

consumption. For EuP ready power supply selection, we recommend you

checking with the power supply manufacturer for more details.

and supports Dual Channel Memory Technology. For dual channel configuration,

you always need to install identical (the same brand, speed, size and chip-

type) DDR3 DIMM pair in the slots of the same color. In other words, you have to

install identical DDR3 DIMM pair in Dual Channel A (DDR3_A1 and DDR3_B1;

Blue slots; see p.2 No.5) or identical DDR3 DIMM pair in Dual Channel B

(DDR3_A2 and DDR3_B2; White slots; see p.2 No.6), so that Dual Channel

Memory Technology can be activated. This motherboard also allows you to

install four DDR3 DIMMs for dual channel configuration, and please install iden-

tical DDR3 DIMMs in all four slots. You may refer to the Dual Channel Memory
